Things You Should Know About a Fiber Laser Engraver
It wouldn’t make sense for us to tell you about the fiber laser engravers we like without giving more information about this equipment. Here’s what you need to know.
What Should I Look For in a Fiber Laser?
Some things you must consider before purchasing a fiber laser engraver include:
- The engraving speed (how fast you can engrave the materials).
- Its price point and if it suits your needs.
- Its durability or portability – whichever is more important for you.
- The features it comes with (a wide range of features is best).
Ask yourself: how do all these features apply to your potential usage of your Fiber Laser Engraving Machine?
It’s best to make an informed purchase decision, and if you have a clear understanding of your requirements, the process is more manageable.
What Can I Do With a Fiber Laser Engraver?
You can accomplish a wide variety of tasks and different types of engravings with laser engravers, such as engraving barcodes, your company or brand’s logo, jewelry personalization, gun engraving and so much more.
From numbers, texts, or even simple clip art, if you can think of it, you can get it marked permanently on any item or material you have available or want, thanks to this new laser technology.
How Does a Fiber Laser Engraver Work?
Laser engraving machine technology works by concentrating a high-powered laser beam made of light into fiber optic cables. This beam is so strong that it can make a permanent mark on a wide variety of materials.
This process is similar to how a magnifying glass can focus sunlight onto a single point. After that, it produces such a strong and tightly-packed laser wavelength that can easily leave deep burn markings onto a surface, just like a permanent engraving.
What Materials Can You Engrave with a Fiber Laser?
Fiber laser engraver machines are technologically advanced, top-of-the-line machinery that can now engrave images and text onto almost any material.
For non-organic materials like metals, engraving onto stainless steel, copper, brass, aluminum, iron, and even precious metals like gold and silver is possible. It can also mark painted, anodized, or coated surfaces.
For organic material, engraving onto leather, PVC, and resin is possible, among other choices. However, it is not ideal for wood, glass, or clear acrylic, as fiber lasers do not interact well with transparent materials. Its wide application and practically endless material capabilities make this technology a virtually unstoppable force for profitable businesses.
Here is the list of materials that you can engrave with a Fiber Laser:
Metals:
- Aluminum
- Gold
- Platinum
- Silver
- Titanium
- Brass
- Tungsten
- Carbide
- Nickel
- Stainless steel
- Chrome
- Copper
Plastics:
- Polycarbonate
- ABS
- Polyethylene
- Polypropylene
- PLA
- PBT
- PVC (Please ensure you have a good fume extraction system as PVC fumes are toxic and corrosive)
Other Materials:
- Fiberglass
- Synthetic Leathers
- Carbon fiber
What’s the Difference Between a CO2 Laser and a Fiber Laser Engraver?
A CO2 laser and a fiber laser have several differences, including the range of materials they can engrave on best. Specifically, for more organic materials such as wood, plastic, and textiles, CO2 lasers are the better choice.
Meanwhile, fiber lasers are the right fit for non-organic materials like metals.
The laser wavelength produced by each option is quite different, with a fiber laser machine having wavelengths of around 1,060 nanometers. In comparison, CO2 Lasers have wavelengths of about 10,600 nanometers, which is at least ten times higher.
This difference has a significant impact on the way each technology works.
CO2 lasers are larger than fiber lasers and are less expensive, so the engraving quality is a bit less. However, markings with fiber laser engravers are very high-contrast and deeper.
Fiber laser marking machines also have much lower maintenance costs and are generally a more cost-effective technology due to their high electrical efficiency compared to CO2 lasers. This means that fiber laser engraver technology is less expensive overall.
However, CO2 lasers are the best option by far if you are looking to mark thicker objects like wood or plastic and can engrave smoothly as deep as 5 millimeters. They have a lower equipment price than fiber lasers but are ultimately an old technology with diminishing usefulness, in addition to their high maintenance cost.
